  1. An assessment of behavioural syndromes in rangeland-raised beef cattle

    Contributor(s):: Wesley, Robert L., Cibils, Andrés F., Mulliniks, J. Travis, Pollak, Emily R., Petersen, Mark K., Fredrickson, Ed L.

    Individuals in most animal groups exhibit consistent behavioural differences across situations or over time known as behavioural syndromes. We conducted a study with a herd of young rangeland-raised cows to determine whether animals exhibited consistent differences in foraging behaviours across...

  2. Microhabitat selection of free-ranging beef cattle in south-boreal forest

    Contributor(s):: Spedener, Mélanie, Tofastrud, Morten, Devineau, Olivier, Zimmermann, Barbara

    Cattle released for summer grazing in south-boreal forest are free to select among a broad range of habitats. The goal of this study was to identify the factors influencing the microhabitat selection of such free-ranging beef cattle, for grazing and resting. We equipped sixteen female adult cows...

  3. Associations between precision sensor data with productivity, health and welfare indicator traits in native black and white dual-purpose cattle under grazing conditions

    Contributor(s):: Jaeger, Maria, Brügemann, Kerstin, Brandt, Horst, König, Sven

    The aim of the study was to analyse the relationships between conventional production as well as subjectively scored welfare assessment traits with longitudinal sensor measurements (i.e., behavioural activity traits) of dual-purpose cattle kept in grazing systems. Such aim implies getting...

  4. Behaviour of White Fulani calves grazing panicum/stylo pasture in Southwest Nigeria

    Contributor(s):: Jimoh, Saheed Olaide, Adeleye, Oluwagbemiga Olanrewaju, Dele, Peter Aniwe, Amisu, Ahmed Adeyemi, Olalekan, Qayyum Olawunmi, Jolaosho, Oluwafunmilayo Alaba, Olanite, Jimoh Alao

    The objective of this study was to investigate the behaviour of White Fulani (WF) yearling calves grazing a Panicum maximum/Stylosanthes guianensis mixture under traditional management system in south western Nigeria. The effects of two biomass spatial distribution (dense and sparse) were...

  5. Behavioral patterns of (co-)grazing cattle and sheep on swards differing in plant diversity

    Contributor(s):: Cuchillo Hilario, Mario, Wrage-Mönnig, Nicole, Isselstein, Johannes

    Both botanical composition and the presence of additional grazer species may modify the grazing efficiency and ingestive behavior of ruminants. However, at present, potential effects of interactions between sward diversity and presence of multiple animal species on the grazing behavior of cattle...

  6. Effects of early experience and alternative feeds on medusahead (Taeniatherum caput-medusae ssp. asperum) intake by sheep

    Contributor(s):: Montes-Sánchez, Juan J., Villalba, Juan J.

    The goals of this study were to test the effects of early experience at grazing medusahead – an invasive unpalatable weed – and the availability of forage alternatives on intake of medusahead later in life by sheep. The study involved two experiments of 10 days each. During Experiment 1, 29...

  7. Spatial and temporal activity of cattle grazing in Mediterranean oak woodland

    Contributor(s):: Schoenbaum, Iris, Kigel, Jaime, Ungar, Eugene D., Dolev, Amit, Henkin, Zalmen

    We examined the temporal and spatial variation patterns of the grazing activity of free-ranging cattle in Mediterranean oak woodland in the Western Galilee, Israel, as affected by seasonal and management factors. The vegetation is dominated by scrub-oak woodland (Quercus calliprinos Webb.),...

  8. Daytime summer access to pasture vs. free-stall barn in dairy cows with year-long outdoor experience: A case study

    Contributor(s):: Shepley, Elise, Bergeron, Reneé, Vasseur, Elsa

    With its documented health and behavioural benefits, one would expect dairy cows to have near unconditional preference for pasture. However, dairy cow preference is multifaceted with numerous factors contributing to the choices and or actions of the cow. Experience is one such factor that may...

  9. Using a three-axis accelerometer to identify and classify sheep behaviour at pasture

    Contributor(s):: Alvarenga, F. A. P., Borges, I., Palkovič, L., Rodina, J., Oddy, V. H., Dobos, R. C.

    Identifying and classifying feeding behaviour in free-ranging ruminants will help improve efficiency of animal production. Another potential benefit would be in understanding the role behaviour has in determining heritability of methane measurement. The aim of this study was to determine the...

  10. Targeted grazing of milk thistle (Silybum marianum) and Syrian thistle (Notobasis syriaca) by goats: Preference following preconditioning, generational transfer, and toxicity

    Contributor(s):: Arviv, A., Muklada, H., Kigel, J., Voet, H., Glasser, T., Dvash, L., Ungar, E. D., Landau, S. Y.

    Nitrophilic thistles such as milk thistle (Sylibum marianum) and Syrian thistle (Notobasis syriaca) encroach rangeland areas where animals gather and defecate, in particular around watering and feeding points. High densities of milk and Syrian thistles (MST) diminish forage yields and detract...

  11. A modeling approach for estimating seasonal dietary preferences of goats in a Mediterranean Quercus frainetto–Juniperus oxycedrus woodland

    Contributor(s):: Manousidis, T., Malesios, C., Kyriazopoulos, A. P., Parissi, Z. M., Abraham, E. M., Abas, Z.

    Goats are characterized as selective feeders due to their specific feeding behavior, thus the study of their seasonal preferences in a Mediterranean oak-juniper ecosystem is of great interest. The current research was conducted in an open oak forest in Megalo Dereio region, northeastern Greece...

  12. Behavioural response of pure Ankole and crossbred (Ankole×Holstein) cows to seasonal pasture variations in south-western Uganda

    Contributor(s):: Idibu, Joachine, Kabi, Fred, Mpairwe, Denis

    This study evaluated the effects of season and pasture species on variations in sward composition, pasture quantity (plant-height and biomass) and quality [crude protein (CP), neutral detergent fibre (NDF) and in vitro organic matter digestibility (IVOMD)]. Behavioural responses of a group of 10...

  13. Location of supplementary feed and water troughs on the sward affects movement and spatial distribution of Brahman cattle (Bos indicus)

    Contributor(s):: Solano, Jaime, Averós, Xavier, Clemente, Neftalí, Aguirre, Virginio, Estevez, Inma, Orihuela, Agustín

    The grazing dynamics of animals differ depending on whether they are raised on rangeland or sward areas. Grazing patterns of cattle raised on rangeland can be modified by the location of supplement feed and water troughs. However, no information about the use of this strategy is available for...

  14. Influence of off-stream watering systems on cattle behaviour adjacent to Lower Little Bow River in Southern Alberta

    Contributor(s):: Miller, J. J., Curtis, T., Rogness, D., Willms, W. D., Chanasyk, D. S.

    Off-stream waterers (OSWs) located in upland pastures may be effective in reducing livestock impacts on riparian areas and rivers, but little research has been conducted on the impact of OSWs located closer to rivers. We studied cattle behaviour over four years (2012-2015) for a portable OSW at...

  15. Brazilian Citizens: Expectations Regarding Dairy Cattle Welfare and Awareness of Contentious Practices

    Contributor(s):: Clarissa S. Cardoso, Marina A.G. von Keyserlingk, Marie Jose Hotzel

    The primary aim of this study was to explore attitudes of urban Brazilian citizens about dairy production. A secondary aim was to determine their knowledge and attitudes about four potentially contentious routine dairy cattle management practices: early cow-calf separation; zero-grazing; culling...

  16. Human-Managed vs. Natural Grazing Systems: Exploring Effects of Livestock and Wildlife Grazing at Multiple Scales

    Contributor(s):: Megan Esther McSherry

    Grazing by large herbivores is the most prevalent land use on grassland ecosystems, which cover greater than 40% of the earth's land surface and provide critical ecological and economic benefits. As such, understanding how grazing impacts different aspects of the ecosystem is of especially...
